Question
A light ray travels from vacuum into a slab of material with index of refraction n1 with incident angle ?. It subsequently passes into a second slab of material with index of refraction n2 before passing back into vacuum again. The surfaces of the different materials are all parallel to one another. As the light exits the second slab, what can be said of the final angle ? that the light makes with the normal?a.The angle depends on the magnitudes of n1 and n2.
b. The angle depends on the wavelengths of the light.
c. ? < ?
d.? > ?
e. ? = ?
Explanation / Answer
n1sin i = n2sin2 = n1sinf
hencei=f
